Features: 1With the ability to solve the problem of slow start of 1-20KW low power motor, such three-phase motor soft start module can be easily installed. 2And motor start module enables to make replacement of soft start to inverter or soft star-delta starting , etc. 3Keeps super simple wiring, motor start board is powerful and there is no need to connect bypass contactor. 4Meanwhile, motor controller can be used widely for water pump, fan, air vehicle or ordinary motor soft start. 5Made by exquisite craftsmanship, soft start controller installation does require particularly complicated operations. Item Type: Motor controller Model: TSR-80WA-R18KW(with soft start without soft stop) Suitable for Three-Phase: 380V Compatible: 50-60HZ Radiator Voltage: Default 220VAC Soft Start Time : 30 seconds adjustable (time rising refers to 0-380V). Starting Voltage: Adjustable slow start from 150-250V to rated voltage (380V) Two Ways Use: 1. While switch closed, the soft start of the main power supply starts. 2. Use switch to control, start by closing the soft start, stop when disconnected. Selection: 10A below 1KW, 20A below 2KW, 40A from 3-4KW, 60A from 5-6KW, 80A from 7-8KW, 100A from 8-10KW, 150A from 11-15KW, 200A from 20KW.If the heat sink is larger, the heat sink should also be matched. Applicable Places: Widely used in fans, pumps, belt conveyors, ball mills, conveyors and compressors as an excellent replacement for traditional for star-delta conversion, auto-coupling voltage reduction, magnetron voltage reduction, frequency converter and other voltage reduction starting equipment, safe and reliable. 1 x Overall (Module + Radiator)
